The condenser's primary function is to to?

• A. to condense the refrigerant
• B. to absorb heat from the room
• C. to increase refrigerant pressure
• D. to reject the heat absorbed by the refrigerant of the evaporator

Answer: (D)

The condenser’s job is to reject the heat that the refrigerant has absorbed earlier in the cycle. After compression, the refrigerant is a hot, high-pressure gas. In the condenser, it releases that heat to the outside air and changes into a high-pressure liquid. This heat rejection is what drives the condensation process and prepares the refrigerant to cycle back through the system.

So, while condensation does happen in the condenser, the primary purpose is to reject heat to the outdoor environment. The other options aren’t correct because absorbing heat from the room happens in the evaporator, and increasing refrigerant pressure is the function of the compressor.
